pg. 277 # 1-5 1. Temperature is the average kinetic energy while thermal energy is the energy in the particles. 2. Heat is the measure of energy between 2 objects at different temperatures and the thermal energy is the measure of the energy in the particles. 3. In a conductor, charges can move easily, but in an insulator charges can not move easily. 4. Conduction is the transfer of energy through direct contact and convection is through space and matter by electromagnetic waves. 5. States of matter are the physical forms that substances exist and the changes of the states are the change of one physical form to another. ----
Density of Air lab Mass Procedures: 1.We took the air out of the falsk. 2.Find mass of the empty flask with the rubber stopper adn the black piece. 3.Subtract the mass of the 2 rubber parts from the mass of the empty flask. || Empty Flask (g) || 113.7 || || Flask with Air (g) || 95.6 || || Mass of Air (g) || 0.2 mass || Volume Procedures: 1.Fill flask up 2. Pour into gradulated cylinder up to 100ml each bit. 3.Add all measurements together. 100+100+65=265 volume Density= .0007g/cm^3 ----
For our lab we decided to measure what melted faster sugar, salt, or just regular ice. Here is our data... || Solute (g) || Time (min) || Trials || || Salt || 43:02 || 1 || || Sugar || 48:11 || 1 || || No solute || 54:28 || 1 || Purpose- What would melt faster salt or suagr? Hypothesis- I think that the sakt will make the ive melt faster. Independant Variable- Amount of salt and sugar Dependant Variable- How fast the ice melts. Constants- Amount of solute, amount of ice Procedures- 1. Fill three beakers with 30g of ice. 2. Fill 1 beaker with 5 g of salt and fill 1 beakewr with 5g of sugar and leave the last beaker alone. 3. Record the time it takes for all of the ice to melt into a liquid.===
